Fortunately, it seems as if the sixth-gen iPhone, rumored to arrive in October 2012, may finally support high-speed 4G LTE connectivity. This certainly seem plausible, especially following the debut of Apple's new 4G LTE-enabled iPad.
According to iMore, the next iteration of the iPhone will feature the same size 3.5-inch screen; however, Reuters claims the new handset will boast a much larger 4.6-inch Retina display.
As AppleInsider's Sam Oliver points out, the 4.6-inch Retina rumor seems rather unlikely, as it would present "complications" for devs coding apps targeted at the smartphone's current 3.5-inch Retina display.
Of course, apps could be updated and tweaked, although judging by past product releases, it does seem as if Apple prefers sticking with a particular form factor and size for as long as possible.
iMore also claims that Apple may be looking to replace its 30-pin dock connector currently found in the iPhone, iPad and iPod. The new port will reportedly be a smaller, space saving component that is likely to debut on the new iPhone.
Although Apple has yet to confirm the new handset, rumors of a next-gen iPhone continue to churn, with Barclays analysts confirming that Cupertino is currently reviewing potential components for its future "world" device handset - which is likely to utilize Qualcomm's "MDM9615" LTE chip and support both voice and data connections over high-speed 4G networks.
